TCL TV Error 014 after a router restart usually means the router reboot cleared a temporary glitch, but the TV still cannot complete the Wi‑Fi handshake or get a stable IP, so the same code pops back up. The fix is to treat Error 014 as a network‑setup and Wi‑Fi‑authentication problem rather than a hardware fault, and follow a structured sequence of checks after the router has already been restarted.
1. Confirm that the router is actually working
Even though you already restarted the router, check:
-
Other devices (phone, laptop, tablet) can connect to the same Wi‑Fi network and load websites or apps.
-
Your router’s internet light is solid (not blinking red or disconnected).
If other devices fail as well, the issue is still with the router or ISP, not the TCL TV, and you may need to reboot the modem, reset the router to factory, or contact your ISP before retrying the TV.
2. Re‑enter Wi‑Fi details on the TCL TV
After a router restart, saved Wi‑Fi data on the TV can mismatch the new router state, so Error 014 often clears by re‑typing the network information:
-
On the TCL Roku TV, go to Home → Settings → Network → Set up connection → Wireless.
-
Select your Wi‑Fi network by name and re‑type the password carefully; passwords are case‑sensitive.
-
If your router supports 2.4 GHz and 5 GHz, try both bands to see which one connects cleanly.
If the TV finally connects after this, the router restart only fixed the upstream issue; the TV still needed fresh Wi‑Fi credentials.
3. Forget the network and reconnect
If the TV used to connect but stopped after the router restart:
-
Under Network → Set up connection → Wireless, select your network and choose Forget network (if the option appears).
-
Then run Set up connection again and re‑enter the Wi‑Fi password.
This wipes the old Wi‑Fi profile and forces the TV to create a clean new one, which often fixes Error 014 when the router configuration changed after the restart.
4. Check router‑side settings (password, MAC filtering, DHCP)
Even after a router restart, Error 014.40, 014.41, 014.20, and similar variants often appear because of router settings that block or confuse the TV.
-
Confirm Wi‑Fi password on the router label or admin page and match it exactly on the TV (use copy‑type or voice‑to‑text on a phone if possible).
-
Check MAC address filtering / Access Control in the router admin page; if enabled, either:
-
Disable it temporarily, or
-
Add the TV’s MAC (found in Settings → Network → Network status → Wireless MAC) to the allowed list.
-
-
Ensure DHCP is enabled and the TV is getting an IP address; if the TV says “connected to network” but Error 014 persists, DHCP failure or router firewall rules can be the cause.
Save router changes, restart the router again, then reconnect the TCL TV; in many cases this eliminates Error 014 after restarts.
5. Improve Wi‑Fi signal and environment
If the code is 014.20 / 014.30 / 014.50, TCL’s support notes that the TV is not receiving a strong enough Wi‑Fi signal even after a router restart.
To fix this:
-
Move the TV closer to the router or move the router to a more central, open location.
-
Avoid placing the router inside a metal cabinet or on a shelf with thick walls between it and the TV.
-
If possible, connect the TCL TV to the router using an Ethernet cable temporarily to prove the internet is fine; if streaming works over Ethernet, the issue is purely Wi‑Fi signal strength or router‑radio settings.
Once the TV has a stable connection, you can decide whether to keep Ethernet or tune the Wi‑Fi (for example, 2.4 GHz vs 5 GHz or router channel) for long‑term use.
6. Reset network or TV settings if 014 still returns
If Error 014 keeps coming back after a router restart plus the above steps:
-
Reset the network connection via Settings → Network → Reset connection or a similar “Reset network” option.
-
As a final user‑level fix, perform a factory reset on the TCL TV: Settings → System → Advanced system settings → Factory reset. After setup, reconnect to Wi‑Fi. If the TV finally connects without Error 014, the fault was in corrupted network or system settings, not the router or Wi‑Fi module.
For TCL TV owners in Nairobi or similar areas, this whole stack—router‑restart, Wi‑Fi‑re‑entry, router‑side setting checks, and then network reset or factory reset—is what usually stops Error 014 from recurring after a router reboot.
